# Example hash check (if provided) sha256sum P003-9-4-2-11-2.sbn Check digital signature: Cisco firmware is signed. The phone will reject unsigned files. Downloading firmware for the Cisco IP Phone 7965 is straightforward only for users with an active Cisco service contract. Unauthorized sources pose security and integrity risks. Given the EOL status, organizations should consider migrating to supported models (e.g., 8800 series) rather than investing time in legacy firmware management.
If you must keep 7965 phones operational, use a valid Cisco account to download the last SCCP firmware 9.4(2)SR2 or SIP 9.4(2)SR2 from the official portal, and isolate the phones to a secure VoIP VLAN with no internet access.
